sorting a list in python is a common task that can be accomplished using built-in methods. in this tutorial, i'll explain various ways to sort a list, including using the `sort()` method and the `sorted()` function, along with examples.
1. using `sort()`
the `sort()` method sorts the list in place. this means the original list is modified, and it does not return a new list.
#### example
*output:*
2. using `sorted()`
the `sorted()` function returns a new sorted list from the elements of any iterable (like lists, tuples, etc.). the original list remains unchanged.
#### example
*output:*
3. sorting in descending order
both `sort()` and `sorted()` accept the `reverse` parameter. set `reverse=true` to sort in descending order.
#### example with `sort()`
*output:*
#### example with `sorted()`
*output:*
4. sorting with a custom key
you can also sort lists using a custom key by passing a function to the `key` parameter. this is useful for sorting complex data structures or when you need to sort based on specific attributes.
#### example with a list of tuples
*output:*
conclusion
in this tutorial, we've covered how to sort lists in python using the `sort()` method and the `sorted()` function. we also explored sorting in descending order and using custom keys. sorting is a fundamental operation in programming, and python makes it easy to implement with these built-in methods. happy coding!
